fix: add --n-jobs-per-worker 10 to langgraph dev command in Docker (#1623)
`langgraph dev` defaults `n_jobs_per_worker` to 1 when the flag is not
explicitly passed (see langgraph_api/cli.py), even though the
`N_JOBS_PER_WORKER` env-var default is 10.

This causes the LangGraph server to run with a single background worker,
meaning all conversation runs are processed serially. When one run is
busy (e.g. summarization or long tool-calling chains), all other threads
are blocked until it finishes.

Add `--n-jobs-per-worker 10` to both production and dev Docker Compose
files to match the intended default concurrency.
